IMPROVEMENT INl NILGANIATRS.

To all whom it may concern:

Be it known that I, FREDRIGK Monats, of San Francisco city and county, State of Galifornia, have invented an Improved Settler for Separating Gold and Silver; and I do hereby declare the following description and accom panying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement Without further invention or experiment.

My invention relates to improvements in the vessels which are used for settling orepulp in order to separate the heavy particles from the mud and slime'after the pulp has passed through the grinding and amalgamat ing process. Y

In order to more fully explain myinvention reference is had to the accompanying drawing forming a part of this specification, in which- Figure l is a sectional elevation of my settler. Fig. 2 is a plan view.

A represents a 4tub or vessel, which can be made of Wood or iron, in the center of which rises the muller-supporting standard b. The bottom of this vessel I cover with a layer of Wooden bloc-11s,@ c, placed with the grain standing vertically. Radiating Wooden strips d d separate the sections of blocks` c c at intervals extending from the center to the outer edge ot' the bottom. These strips d d consist of boards placed edgewise between the triangular sections of blocks and so that their upper edges will be somewhat lower than the surface of the blocks c c. Around the outer edge of the bottom I make a channel or deep groove, f, between this wooden bottom and the side of the vessel, for the purpose hereinafter explained. The muller G I also construct of Wooden blocks secured to the mullerarms with the grain of the wood standing vertically, so that all of the wear upon the muller and bottom will be upon the end of the grain of Wood.

By employing wood in this mannerfor the bottom of the tub and for the muller--much better results can be obtained in the process of settling. The channel formed by the depressed strips d d serves to convey any particles of quicksilver, which may become separated, to the annular channel faround the edge of the bottom of the vessel.

In order to draw oft the Water from the vessel I employ a siphon, h, which is secured upon the edge of side of the vessel so that its inside leg will come almost to the center ot' the pan. By means of this siphon I am enabled to draw oft the tailings or slime from the center of the vessel, where, .by reason of a less amount of agitation than at the sides, an eddy is formed, which is more favorable for allowing the heavier particles to settle than at any other point in the vessel, While at and near the sides the greater speed of the muller keeps the pulp in constant motion, so that a portion of the amalgam will always be drawn oi' with the tailings when the discharge is at the side;

By these improvements I greatly facilitate,

the separation ofthe gold and silver from the pulp.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. 'Ihe tub or vessel A, having its bottom covered with Wood placed with the grain ver tically, and having the depressed radial strip d d and outer annular channel f, substantially as and for the purpose above described.

2. The tub or vessel A, having its bottoni covered With Wood placed With the grain vertieally, in combination With the Wooden muller G, substantially as and for the purpose above described.

3. The siphon h, in combination with the settling-vessel A, substantially as and for the purpose above described.

In Witness whereof I have hereunto set my hand and seal.
